We divide 777046 by 91
The aim is to understand the frequency of 91 in 777046.

Moving on to step 1:
The number 91 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 91

On to step 2:
If we divide 77 by 91, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 91

Going ahead to step 3:
777 divided by 91 is 8 with a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 728 from 777 to get 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 91

Step 4:
91 goes into 490 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 455 from 490 leaves us with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 91

On to step 5:
If we divide 354 by 91, we get 3 and a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 853.0
The remainder is 81 after subtracting 273 from 354.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 91

Step 6:
When dividing 816 by 91, we get 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 8538.0
The remainder is 88 after subtracting 728 from 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 7:
When dividing 880 by 91, we get 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 8538.9
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 8:
610 divided by 91 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 8538.96
If we take 546 away from 610, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
When dividing 640 by 91, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 8538.967
If we subtract 637 from 640, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
If we divide 30 by 91, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8538.967
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 91, we get 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 8538.96703
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
91 can be fit into 270 2 times, resulting in a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 8538.967032
Subtract 182 from 270 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 13:
880 divided by 91 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 8538.9670329
If we take 819 away from 880, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
610 divided by 91 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 8538.96703296
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 8538.96703296 with a remainder of 6.4e-08.
